Blazing Fast NICs for Linux
NetXen is offering drivers and software for its 10 Gigabit per second Etherent cards that will bring new high-performance networking to Linux servers. (Linux-Watch)NetXen, a maker of hardware-accelerated 10GbE (10-Gigabit Ethernet) LAN cards, has just introduced a set of software drivers for Linux systems. The company claims that with this hardware/software combo users should see great network performance without incurring increased host CPU overhead. NetXen says its network acceleration technology requires no modifications to the Linux kernel or the TCP/IP network stack or applications, and can offload both user- and kernel-mode applications. Using a driver technology called LSA (Linux Sockets Acceleration), the technology provides stateful network acceleration. In a stateful network, network devices track the condition of network connections.
This information is vital for providing QoS (quality of service) services. Unfortunately, tracking stateful information can eat up 70 to 80 percent of your network processing workload.
